One of the more curious aspects of the war is the lack of Russian air power in the skies. In a November 2021 report from Flight International, the Ukrainian Air Force fielded 37 Mikoyan MiG-29 Fulcrum multi-role fighters, 12 Sukhoi Su-24 Fencer attack jets, 17 Su-25 Frogfoot attack/close air support jets, and 32 Su-27 Flanker multi-role fighters. Against these 98 combat aircraft (Ukraine has no bombers any longer), the Russians have arrayed at least 300 combat aircraft in the region. Yet, even now, Ukrainian pilots are still able to sortie against Russian ground targets and engage in low-level aerial combat with what Russian aviation is about in the sky.
So why is this the case? There are many opinions out there. The first is a lack of PGMs (Precision Guided Munitions) coupled with the inability to accurately deliver said ordnance. The latter is due to inadequate pilot training. It is believed that Russia's inventory of PGMs is very low and thus if any strikes were to be carried out, it would be done with unguided bombs and rockets. By having to use such munitions, it forces the aircraft into range of Ukrainian surface-to-air missiles, especially man-portable ones.
Another factor is the fear that Russian ground forces will shoot first and ask questions later. Considering that a decent portion of Russian troops are conscripts, this fear is very much valid. Combine this with the fact the Ukrainian Air Force flies the same exact types of aircraft the Russian Air Force does, the risk is very real and the last thing the Russian Air Force wants is lost planes due to friendly fire.
Finally, some think that the typical Russian pilot lacks flight hours, and thus the needed skill to engage in actual combat successfully, in comparison to Western pilots. On average, a Russian pilot gets under 100 hours in the cockpit every year while, for example, U.S. Air Force pilots can get up to 240 hours each year.
The photograph here shows an abandoned 2K22 Tunguska somewhere around Kharkiv. The 2K22 is the replacement for the ZSU-23-4 Shilka, a rather lethal self-propelled anti-aircraft gun (SPAAG) that entered service in 1960. So lethal was the Shilka that many NATO nations stated in their infantry combat doctrine that any time a ZSU-23-4 was spotted in a column being ambushed, it was to be destroyed immediately before any other target as the quadruple 23mm cannons would quickly put an end to the attack. Although the Russian Marines still deploy the Shilka, the Russian Army uses the 2K22.
The 2K22 is built on a GM tracked chassis, powered by a V-46-6-MS turbocharged, V-12, fuel-injected, water-cooled diesel engine developing between 780 to 840 horsepower. This gives a top road speed of 40 miles per hour and enough fuel for a 310 mile operational range. The SPAAG is equipped with the Hot Shot (NATO code-name) system that combines a parabolic E-band target acquisition radar (what we see in the folded position in the photograph) with a J-band monopulse tracking radar fitted in the center of the turret front. The target acquisition radar has a 360 degree field of view, can detect aerial targets out to 11 miles and flying as low as 50 feet off the ground. It can track targets starting within 10 miles at an altitude of 2 miles or less. Engagement can occur when the target speed is 1,640 feet per second or less with the response time of the weapon systems being 6-8 seconds. The Hot Shot system is all-weather, day and night.
Speaking of weapons, the 2K22 is fitted with two 2A38M 30mm guns with each gun provided with 1,904 rounds of ammunition. Underneath each gun is a battery of four 9M311 surface-to-air missiles (NATO code-name SA-19 Grison), for a total of eight ready-to-fire missiles. The combined fire of both cannons is 3,900 to 5,000 rounds per minute but the usual is brief bursts of 83 to 250 rounds target depending. The maximum effective range is 2,000 meters while with the 9M311, the maximum range is between 5 miles to 6.2 miles. The missiles cannot be fired while the 2K22 is on the move though the guns can when set to full automatic computer controlled engagement. If need be, the gunner is provided with a stabilized sight for manual engagement, using the radar for range data.
The 2K22's armor protects the four man crew from small arms fire and shell fragments but it is incapable of surviving hits by anything heavier. It is well equipped with good ventilation, heating system, NBC (Nuclear Biological Chemical) system, automatic fire suppression, night vision, extensive communication equipment, and navigational systems.
The Ukrainian Army had, in a 2012 report, 70 Tunguska on strength but built on a 2S6 chassis rather than a GM chassis. How many remain in service now is unknown. It is believed that this example may have ultimately been destroyed by Ukrainian forces. This assumes the Russians rendered the 2K22 unusable prior to abandoning it.
